Txawm tias kev suav ua tib zoo tshaj plaws thiab ua kom haum tuaj yeem ua rau qhov khoob. Thiab tseem muaj qhov tawg thiab tawg tshwm ntawm lub sijhawm sib txawv ntawm kev ua haujlwm ntawm lub tsev tsim qauv. Qhov no tuaj yeem ua rau ib puag ncig cuam tshuam rau huab cua sab hauv tsev. Kev daws rau cov teeb meem no yog txhawm rau nrhiav lub foob nrog cov khoom tsim nyog. Nws yog polyurethane ntau yam uas tau rov ua pov thawj nws qhov ua tau zoo hauv kev ua haujlwm sab nraum zoov.
Khoom
Lub npe nrov ntawm polyurethane sealant nkag siab, vim nws muaj ntau qhov zoo:
- yas - txawm tias tom qab ua kom khov, nws tuaj yeem hloov pauv: nthuav lossis cog lus nrog kev txav ntawm cov khoom sib txuas;
- lub zog - txawm tias muaj peev xwm hloov pauv nws cov duab, hauv lub xeev khov kho nws muab qib zoo ntawm kev sib cais los ntawm txias, dej thiab lwm yam huab cua;
- kav ntev - tsis poob nws cov khoom nyob rau lub sijhawm;
- muaj ntau qhov kev thov ncaj ncees - vim muaj cov nplaum zoo rau feem ntau cov khoom siv hauv tsev;
- tsis ntsws;
- qhuav sai - txuag sijhawm;
- yooj yim siv - qhov sib xws ntawm qhov nruab nrab nruab nrab tso cai rau koj kom muaj kev lag luam thiab raug sau cov kab nrib pleb yam tsis tau qias neeg, thiab tseem yuav tsis ncua kev ua haujlwm txawm tias nyob hauv qhov kub qis;
- yooj yim ntawm kev thov ua tsaug rau cov cuab yeej uas twb muaj lawm;
- tiv taus ya raws, qhov kub tseem ceeb heev, ultraviolet lub teeb, tshuaj lom neeg;
- nws tuaj yeem tsis muaj xim - tsis sawv ntawm qhov keeb kwm yav dhau - lossis xim.
Polyurethane sealant nws muaj nws qhov tshwj xeeb ntawm kev siv
- Muaj cov ntawv txwv. Adhesion rau qee hom yas yuav tsis muaj zog txaus. Nws tau thov nrog ceev faj rau cov khoom siv hauv tsev ntub yog tias cov khoom muaj peev xwm khaws cov dej hauv nws tus kheej. Hauv ob qho xwm txheej no, qhov xwm txheej tuaj yeem raug kho los ntawm kev siv tus txheej txheem tsim nyog.
- Muaj qhov kub thiab txias txwv. Hauv lub xeev khov kho, nws poob nws cov khoom ntawm qhov kub qis dua -60 degrees thiab siab dua +120 degrees Celsius. Hauv qhov kub qis dua -10 degrees, nws tawv tawv heev.
- Qib ntawm polyurethane sealant yuav tsum tau ua tib zoo xaiv. Piv txwv li, yog tias cov khoom sib txuas tau raug nthuav tawm tas li rau qhov cuam tshuam ncaj qha, qhov yuav tsum tau muab rau lub foob nrog qib siab ntawm qhov nyuaj hauv daim ntawv kho.
Saib
Cov insulating muaj pes tsawg leeg tuaj yeem yog qhov sib txawv sib txawv:
- Tsawg ntom (15-25) - rau kev ua haujlwm dav dav: nrog ntoo, yas, iav, ua vaj tsev;
- Qhov nruab nrab (40) - rau cov pob qij txha tas li nyob rau hauv kev sib cuag nrog cov dej noo, nrog rau cov khoom siv nyuaj xws li cov pob zeb txhawb ntxiv;
- Siab (50-60) - nws tuaj yeem tuav cov vuas hlau, ntxiv rau cov nqaws hauv cov tshuab kho tshuab.
Raws li lawv muaj pes tsawg leeg, polyurethane sealants tau muab faib ua ob hom
- Ib-feem. Lawv yog cov nplej zom npaj tau. Curing tshwm sim ib txwm vim muaj kev cuam tshuam nrog huab cua, lossis theej, cov dej noo nyob hauv nws.
- Ob-feem. Cov pob muaj ob lub thawv cais nrog cov khoom tseem ceeb thiab cov tshuaj ntxiv, uas pib txheej txheem kho.
Qhov zoo ntawm ob-kev tiv thaiv yog tias lawv tuaj yeem siv rau hauv cov xwm txheej hnyav dua (ntawm qhov kub tsawg) thiab tsis nyob ntawm qhov av noo.
Cov txheej txheem sib xyaw nqa nrog nws cov teeb meem ntxiv
- Qhov zoo ntawm cov ntawv foob yog nyob ntawm qhov sib piv uas ob qhov sib xyaw tau sib xyaw.
- Kneading yuav siv sij hawm.
- Txhawm rau kom tau txais qhov tseeb, sib npaug hauv qhov sib xws thiab xim, koj yuav tsum siv dag zog.
Qhov nrawm thiab ntev ntawm kev sib tov yuav tsum txaus, txwv tsis pub cov khoom zoo ntawm rwb thaiv tsev thiab kev sib txuas yuav poob ib nrab. Yog li ntawd, nws yog qhov zoo dua rau cov pib xaiv xaiv cov tshuaj ua kom tiav, vim tias ob qho tib si ntawm cov foob foob tau ua haujlwm zoo ib yam hauv daim ntawv thov.
Nws siv qhov twg?
Polyurethane sealant muaj kev nyab xeeb thiab tuaj yeem siv sab hauv tsev. Frost-resistant thiab dej-resistant polyurethane daim ntawv yog qhov muaj txiaj ntsig zoo tshaj plaws hauv kev sib piv nrog lwm cov sealants raws li rwb thaiv tsev thiab txuas ntawm cov nqaws sab nraud.
Polyurethane based sealant tuaj yeem siv rau:
- lub qhov rooj thiab lub qhov rooj thav duab, raws li nws tso cai rau koj kom sov hauv tsev thiab tsis pub cov cua ntsawj ntshab thiab txias nkag mus rau sab nraud;
- facades ntawm lub tsev, chav da dej, gazebos, txij li, ntxiv rau rwb thaiv tsev, nws tsim kom muaj kev sib txuas zoo haum;
- ru tsev - nws nyuaj rau xav txog lwm qhov chaw zoo li no, uas cuam tshuam los ntawm cov xwm txheej ntuj txhua feeb;
- pas dej, cov ciav dej - hauv qhov no, lub foob siv los tiv thaiv dej;
- cov khoom siv hlau, suav nrog tsheb, vim nws tiv taus kev co zoo.
Lawv tuaj yeem nplaum cov khoom sib txawv ntawm qhov sib txawv thiab kev ntxhib los mos. Ntawd yog, los ua ke cov khoom siv hlau thiab hlau, yas thiab pob zeb ua ke. Cov khoom siv polyurethane tshwj xeeb tshaj yog muaj txiaj ntsig thaum ua cov ntaub ntawv uas nquag nthuav dav lossis txo qis (pob zeb, ntoo).
Txhawm rau kom pom tseeb, cia saib ntawm daim ntawv thov txheej txheej polyurethane vov tsev . Hauv qhov no, kev tsim cov txheej txheem sib koom ua ke ntawm cov khoom siv vov tsev (txawm tias nws tau sib tshooj), ib puag ncig ntawm cov ntsia hlau ntawm cov kav cua sov, lub qhov dej, qhov rau qhov cua nkag, thiab lwm yam. Yog tias peb tab tom tham txog lub ntsej muag, tom qab ntawv feem ntau qhov nqaim ntev thiab hla ntawm cov khoom thaiv lossis cov nplais tsev, cov ntoo thiab cov vaj huam sib luag tau ua tiav, thiab lawv kho tom ntej kuj tseem ua tiav.
Cov txheej txheem thov
Cov txheej txheem ntawm kev thov polyurethane sealant rau kev sib koom tes yog qhov yooj yim heev.
- Nws yog qhov tsim nyog los ntxuav qhov chaw so thiab qhov chaw nyob ib sab los ntawm plua plav, av lossis cov tub lim qub. Thaum kub qis dua xoom, dej khov thiab daus yuav tsum tau ua tib zoo tshem tawm. Txhawm rau ua kom lub ntsej muag zoo nkauj, koj yuav tsum siv daim kab xev tsim nyob ib puag ncig ntawm cov nqaws.
- Yog tias koj tsis ntseeg tias muaj pes tsawg leeg yuav haum zoo, sim ua ntawv thov rau cov khoom siv zoo sib xws. Thiab kev qhia ntxiv hauv daim ntawv thov yuav tsis ua mob, vim tias cov foob foob tau teeb tsa sai heev. Nws yuav tuaj yeem kho qhov xwm txheej tsuas yog tshem tawm nws thiab ua txhua txoj haujlwm dua.
- Txoj hauv kev thov cov foob foob nyob ntawm qhov sib koom ua ke dav. Tej zaum koj yuav xav tau cov hlua tshwj xeeb lossis, raws li lawv tseem hu ua, gaskets, ntxiv rau daim kab xev insulating. Foamed polyurethane lossis polyethylene yuav muab cov cua sov ntau dua. Lawv tau muab tso rau hauv lub hauv paus ntawm kev sib sib zog nqus thiab dav.
- Qhov hnyav yog siv los ntawm saum toj no nrog spatula. Koj tuaj yeem siv spatula tsis tu ncua lossis tshwj xeeb nqaim. Yog tias tsim nyog, tuaj yeem muaj ob peb txheej, qhov tseem ceeb yog txhua tus ntawm lawv tsis tshaj 4-5 hli. Cov txheej txheej kawg ua tau zoo.
- Qhov nqaim nqaim thiab nqaim tau ntim nrog rab phom siv. Nyob ntawm qhov ntsuas ntawm kev ua haujlwm, nws tuaj yeem yog cov tshuab, pneumatic lossis hluav taws xob.
- Tom qab ua kom tawv tawv, cov leeg tuaj yeem pleev xim rau.
- Txog kev nyab xeeb yog vim ua haujlwm nrog polyurethane sealant, nws yuav tsum muaj lub tshuab ua pa thiab hnab looj tes tiv thaiv.
